Product Details of HDPE Waterproofing Membrane:
Description:
Fosroc HDPE Waterproofing Membrane is a post applied high performance self-adhesive HDPE membrane for waterproofing application for retaining walls, RC members and basement substructures.Fosroc HDPE Waterproofing Membrane provides water, water vapors protection to water excluding structures and protects concrete from aggressive ground salts, chemicals and hydrocarbons.Fosroc HDPE Waterproofing Membrane is supplied as a membrane with 1.2mm thickness having a self-adhesive glue which helps in bonding to all the casted RC members.
Uses & Advantages:
-
- Basement waterproofing protection to grades 1,2 and 3 as defi need in BS 8102: 2009 & IS 16471 : 2017
- To provide a vapors and waterproof membrane in building and civil engineering structures
- Very good bonding with concrete.
- Simple application – no primers or protection material required.
- Inert product – no risk of a reaction with ponded waste present in the soil after backfilling
- Facilitates flexible construction programming.
- Full range of Berger Fosroc hydrophilic and PVC water stops
- available to provide complete solution to waterproofing of the structure.

Application instruction
Surface preparation
Vertical application: All concrete surfaces must be wood float or shutter finish and free from cavities or projections. All honeycombs, cracks, surface defects and tie rod holes should be repaired using structural grade Berger Fosroc Renderoc repair series. All surfaces must be clean, dry and free from contamination, ice and frost. The substrate shall be free from loose aggregate or other sharp protrusions.The surface should be dry enough, moisture content to be <5% to have a neat bonding with the erected membrane.
Membrane Installation
Cut the membrane to a convenient length for installation. Carefully align the membrane and roll it out with printed coated side facing the concrete. Lay adjacent sheets accurately so they overlap the previous sheet 75mm along the selvedge.When laying adjacent full rolls there should be stagger of halfa roll length to avoid a buildup of end joints in one area. The end joints should be done with 100mm overlap.Start from the bottom of the wall and work progressively removing the release paper in stages. Peel of the release film carefully without disturbing the alignment and press the membrane against the RC member firmly.The membrane should be thoroughly rolled through out the length along with overlaps and joints to ensure complete adhesion between lyres and the RC member
Penetrations
Penetrations e.g pipe entries through HDPE Waterproofing Membrane, require special attention to detail. Refer to more information on details.
Backfilling
Backfi lling material must be free from sharp objects and debris that could damage the HDPE Waterproofing Membrane. It should not contain house bricks, blocks or boulders larger than 50 mm.
Contaminated ground
HDPE Waterproofing Membrane is suitable for use in many contaminated ground applicationseg hydrocarbons, salts etc. Consult local Foroc office for specific advice.
Ancillary products
Fosroc Membrane HDPE Sealed Tape
Double-side Adhesive Flashing tape has two layers of adhesive which bond respectively to the HDPE surface.The specially developed Fosroc Membrane HDPE Sealed Tape work together to form a continuous and integral seal to the structure.Fosroc HDPE Waterproofing Membrane Sealed Tape is an 100mm wide tape used in detail areas including end laps and various tie-ins. It is also used to patch damaged areas in the Fosroc HDPE Waterproofing Membrane.
